All-on-4 is the established gold standard for full-arch restoration — and it works. But a newer, more advanced protocol — 3-on-6 (FP1) — now offers what All-on-4 was never designed to deliver: no fake pink gum bar, preserved natural gum line, six implants, and a limited lifetime guarantee. Here's what you need to know.
All-on-4 (also called All-on-X) is a full-arch dental implant technique that restores an entire arch of missing teeth using four to six strategically placed implants. A single, fixed prosthetic bridge is attached to those implants — meaning patients leave with a stable, non-removable set of teeth instead of traditional dentures.
The procedure has been a major advance in implant dentistry for over 20 years. It gave millions of patients a same-day fixed smile and eliminated the adhesives, slippage, and dietary restrictions of removable dentures.
At Significance Dental Specialists, Dr. Allen Huang has performed hundreds of full-arch cases — including All-on-X. Every case begins with a CBCT 3D cone-beam scan and Simplant or Nobelvision digital planning, not a 2D X-ray and a verbal estimate. His board certification, 20,000+ implants placed, and authorization in both All-on-X and the 3-on-6 protocol mean every patient receives an honest, data-driven recommendation — not a one-size-fits-all sales pitch.

In a standard All-on-X procedure, four implants are placed in the jaw — two near the front and two angled toward the back to maximize contact with available bone. This angled approach is what allows All-on-X to work in patients with moderate bone loss without requiring extensive bone grafts.
A single full-arch prosthetic bridge is then attached to the four implants. In same-day protocols, a temporary bridge is placed on surgery day; the final, permanent bridge follows after osseointegration (typically 3–6 months).
All-on-X solves the "teeth in a day" problem effectively. What it does not solve is aesthetics and bone health at the gum level. Because the single full-arch bar must cover the area where natural gums recede after tooth loss, most All-on-X restorations include a pink acrylic or zirconia gum base — the "fake gum" line that replaces your natural gumline.
This is not a flaw in technique — it is a structural necessity of the single-bar design. But for patients who want a restoration that looks completely natural from every angle, All-on-X has always had this limitation.
3-on-6 (FP1 classification) is a full-arch fixed implant protocol that replaces the single full-arch bar with three separate segmented zirconia bridges — each anchored to six implants. The segmented design is the key difference: because the bridges sit on your own preserved gum line rather than replacing it, there is no pink acrylic base. Your natural gumline stays visible.
Six implants instead of four also means better force distribution, more stable long-term bone health, and a lifetime guarantee that All-on-X simply cannot offer.
Dr. Allen Huang is Las Vegas's only authorized 3-on-6 provider — trained and certified at the official 3-on-6 center in Utah.
Both restore a full arch of missing teeth with fixed, non-removable implant bridges. The differences are in design, aesthetics, bone health, and long-term guarantee.

We recommend 3-on-6 for most full-arch patients because the outcomes are superior. But All-on-X remains a clinically excellent option in specific circumstances:
At Significance Dental Specialists, Dr. Huang evaluates every full-arch patient with a CBCT 3D cone-beam scan, reviews the digital plan with the patient directly, and only then makes a recommendation. If All-on-X genuinely serves you better than 3-on-6, that is what he will tell you. His clinical reputation — 18 consecutive years as Top Doctor in Las Vegas — was built on honest assessments, not upsells.
Every full-arch case is different. Use these guides to understand all of your options before your consultation.
Schedule a private consultation with Dr. Allen Huang — Las Vegas’s only Board-Certified Periodontist offering both All-on-X and the 3-on-6 protocol. You’ll leave with an honest recommendation and a complete treatment plan.
